Emprego de um modelo de dispersão turbulento no estudo da universalidade da taxa de dissipação da energia
(Universidade Federal de Santa Maria, 2010-08-13)
This study employed different autocorrelation functions and Maclaurin series expansions in the derivation of expressions describing the dissipation rate of turbulent kinetic energy. These expressions have the same functional ...
Uma visão ampliada sobre os jatos de baixos níveis na América do Sul
(Universidade Federal de Santa Maria, 2019-04-26)
Recently, Oliveira, Nascimento and Kannenberg (2018) [ONK18] showed that the criteria
employed in algorithms that identify low level jet (LLJ) traditionally used in South America
